J1939 CAN BUS CONNECTION

The J1939 CAN (Controller Area Network) Bus is a communications standard designed to permit vehicle devices to communicate with each other. To enable the full range of the Autovue® LDW system by Bendix CVS features, the designated wires in the harness need to be connected to the J1939 CAN Bus.

NOTE: For vehicles built since 2005, the J1939 CAN Bus is almost always activated. In rare cases where J1939 CAN Bus is not found, see the Troubleshooting section.

Most vehicles have a 6- or 9-pin diagnostic connector, near the driver-side door, typically low down on — or under — the dash. See Figures 4 and 5. This connector is used by PC Diagnostics to examine engine performance data and Diagnostic Trouble Codes (DTCs), and is an ideal point to connect the AutoVue LDW system harness.

Gain access to the wires behind the connector. A yellow and green twisted pair of wires is the Standard for J1939 CAN Bus wiring; see the AutoVue LDW system harness
